Important: Any significant MATLAB calculation (takes more than about 5 minutes or a gigabyte of memory) must be submitted to the scheduler.
To see a list of the MATLAB toolboxes available with the license and cluster you're using, you can use the following ~]$ module load ~]$ matlab -nodisplay -nojvm -batch "ver" matlab symbolic link that makes sure that the MATLAB profile and job data will be written to the /scratch space ~]$ cd ~]$ if then Please write to technical support so that we can arrange this for you.īecause the /home directory is accessible in read-only mode on some clusters' compute nodes, users should create a. This will require our technical team to get in touch with the technical people managing your license software. Next you will need to ensure that the license server on your campus is reachable by our compute nodes. Put this file in the $HOME/.licenses/ directory where the IP address and port number correspond to the values for your campus license server. Create a file similar to the following example: If you are allowed, then some technical configuration will be required. Find out who administers the MATLAB license at your institution (faculty, department) and contact them or your Mathworks account manager to know if you are allowed to use the license in this way. Otherwise, either your institution does not have a MATLAB license, does not allow its use in this way, or no arrangements have yet been made. If you get the message This version is newer than the version of the license.dat file and/or network license manager on the server machine, try an older version of MATLAB in the module load line. Be sure to run this test on each cluster on which you want to use MATLAB, since licenses may not be available everywhere.
If any license number is printed, you're okay. To see if you already have access to a license, carry out the following ~]$ module load ~]$ matlab -nodisplay -nojvm -batch ~]$ Arrangements have already been made with several Canadian institutions to make this automatic. This means that we have MATLAB installed on our clusters and can allow you to access an external license to run computations on our infrastructure.
The code is reproduced here: function varargout = tern(condition, true_action, false_action) There is now a tern function on the MathWorks file exchange: Cons: Works only for numeric types, and might fail when T or F are NaN.Note that this solution fits the particular requirements of the initial question with max(C,0). Cons: Works only for numeric types, and might fail when T or F are NaN or Inf.
Can't be used inline, but through the variable tern. Pros: Works for any type and any value.Note that the logical operators are short-circuited. Logical operators and eval ( bool & eval('tern=T') ) || eval('tern=F') Cons: Before returning the result to tern, both T and F.MATLAB does not allow direct indexation of fresh arrays, hence the use of subsref. The vector array version is a specialization for numeric types.
Note that T and F have been swapped, and that different brackets are used. MATLAB has no ternary operator, however it can be implemented in different ways as an inline expression. Returns T if bool evaluates to true, F otherwise. What you refer to is a ternary operator, in C-like notation, ?.
